An accurate and easy to read glass tube thermometer with a plastic backer. Its suction cup allows the thermometer to be positioned anywhere on the inside tank surface. Has a green safety zone indicator to show the best temperature range for most tropical fish. Each thermometer measures approximately 5-1/2" tall. Range: 0 to 40 degrees Celsius and 30 to 100 degrees Fahrenheit. For fresh or saltwater use.

The fish constantly knock the thermometer out of the suction cup. Algae loves to grow on the white plastic. The glass tube is not all that securely fastened so it "slips" giving a different reading. No rubber suction cup lasts forever.
